To determine how you are related: first add the additional boxes to your ancestorGo to the top of the chart. That is your common ancestor.The next line of boxes are siblings.The next line of boxes are first cousins. More cousins follow - second cousins, etc. If there are uneven boxes, that is the number 'removed' - i.e. fourth cousins, 3 times removed means there will be 5 rows of double boxes (cousins) and 3 rows of single boxes (removed)
